Netui tag problem in Firefox

[ptanmoy]

I am facing javascript problem when am using netui tags in weblogic 8.1 with Firefox.
My script is like shown below:
function callSubmit(){
var strName = document[getNetuiTagName('SubmitForm')][getNetuiTagName('name')].value;
alert(strName);
}

The above code runs perfectly in IE but not in Firefox. This gives a javascript error!!
Can anybody help??

What is the error that it gives and on what is the coding of the line error?

I have found out the solution finally...
rather than scripting it like:
document[getNetuiTagName('submitForm')][getNetuiTagName('name')].value;

use:
document.forms[0][getNetuiTagName('name')].value;

This works both in IE and Firefox...as well as in Netscape.

Yes, that will work, but it might cause warnings in Firefox.

The proper way is to give an ID to tags.

<input type="text" id="screenname" value="peejavery">

<script language="JavaScript">
alert(document.getElementById('screenname').value);
</script>
